Relative hsp70 mRNA expression levels after 1-h heat shock in S. purpuratus gastrulae and 4-arm plutei of adults from FC (gastrulae, n = 2; 4-arm plutei, n = 3); SC (gastrulae, n = 3; 4-arm plutei, n = 3); SB (gastrulae, n = 3; 4-arm plutei, n = 4); and ER (gastrulae, n = 3; 4-arm plutei, n = 4). Values are relative to a common S. purpuratus larval standard and normalized to ef1-α. Error bars indicate standard error of male–female pair replicates
